Unique water-based treatment for stone floors. Seals floors and grout without leaving a film, allowing the floor to “breathe". Covers up to three times more square footage than other penetrating sealers, up to 3,000 sq ft per gallon. Protects floors from stains and soil penetration. Allows for easy, convenient application, just pour directly on floor and spread with a squeegee. For use on sandstone, concrete, unglazed ceramic tile, granite, marble and all porous stone floors. Does not alter the floor's slip resistance.
